The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail, and object is to help those skilled in the art to have more complete, accurate and deep understanding to design of the present invention, technical scheme, and contributes to its enforcement.
The preparation technology of a kind of cold curing wet method of the present invention prepreg is by adopting prepreg machine to carry out the production of cold curing wet method prepreg, Figure 1 shows that the structure diagram of this prepreg machine.This preparation technology comprises following step:
Blowing step: the base material of rolling 8 is placed on emptying roller 1, the first barrier film 9 of rolling is placed on the first film discharging roller 3, the second barrier film 10 of rolling is placed on the second film discharging roller 5, and traction base material 8, the first barrier film 9 and the second barrier film 10 are towards same direction traveling priority;
Glue spraying step: use glue-spraying device 2 colloid to be sprayed on the surface of base material 8;
Overlay film step: the extruding by the first compression roller 4 of arranging on base material 8 travel paths, is compounded in the first barrier film 9 and the second barrier film 10 on two surfaces of base material 8;
Cutting step: use cutting knife 7 to cover film formed material and to be cut into laying required size by base material 8, the first barrier film 9, the second barrier film 10.
On prepreg machine, emptying roller 1, the first film discharging roller 3 and the second film discharging roller 5 are the devices as blowing, as shown in Figure 1, emptying roller 1 is positioned at the top of the second film discharging roller 5, on the direct of travel of base material 8, the first film discharging roller 3 is the tops that are positioned at the place ahead of emptying roller 1 and are positioned at base material 8, and emptying roller 1 is parallel with the axis of the second film discharging roller 5 with the first film discharging roller 3, thereby make the first barrier film 9 be positioned at the top of base material 8, make the second barrier film 10 be positioned at the below of base material 8.
On prepreg machine, glue-spraying device 2 is the devices for storing colloid and colloid outwards can being sprayed, and it mainly comprises compression pump and glue spraying head, and compression pump is filled with gas by tracheae in glue spraying head, and the gas being filled with impels the colloid in glue spraying head outwards to spray.As shown in Figure 1, glue-spraying device 2 is positioned at the top of base material 8, and on the direct of travel of base material 8, glue-spraying device 2 is vertically to arrange between the first compression roller 4 and the second compression roller 6, for advance to before the first compression roller 4 the base material 8 upper surfaces spraying colloids to process below it at base material 8.Glue-spraying device 2 is that the compressed air producing by compression pump impels the colloid in glue spraying head to spray to the upper surface of the base material 8 in traveling priority state, so in glue spraying step, can control glue spraying speed and glue spraying amount by adjusting air pressure size.
On prepreg machine, the first compression roller 4 and the second compression roller 6 are paired setting, the second compression roller 6 is provided in a side of between glue-spraying device 2 and the second film discharging roller 5 and emptying roller 1, in blowing step, the second barrier film 10 is advanced towards same direction with base material 8 below base material 8, and the second barrier film 10 and base material 8 are together from the passing between two the second compression rollers 6 up and down of paired setting, and the gap between two the second compression rollers 6 is smaller.On the direct of travel of base material 8, the first compression roller 4 is the place aheads that are positioned at glue-spraying device 2, and be positioned at the rear of cutting knife 7, in blowing step, the first barrier film 9 is advanced towards same direction with base material 8 above base material 8, and the first barrier film 9 and passing between two the first compression rollers 4 up and down from paired setting together with the base material 8 of the second compression roller 6 and the second barrier film 10, gap between two the first compression rollers 4 is also smaller, two compression rollers that arrange in pairs have squeezing action to the object by between the two, thereby the first barrier film 9, base material 8 and the second barrier film 10 can be subject to the extruding of the first compression roller 4 when through the first compression roller 4, and the colloid of base material 8 upper surfaces sprayings can be dispersed in base material 8 upper surfaces after being squeezed, after being squeezed, colloid also can be penetrated into the lower surface of base material 8, make two surfaces up and down of base material 8 have colloid, thereby can be so that the first barrier film 9 and the second barrier film 10 fit tightly with base material 8.
The first above-mentioned compression roller 4 and the axis of the second compression roller 6 are parallel with the axis of emptying roller 1, and in the present embodiment, the first compression roller 4 and the second compression roller 6 are respectively provided with a pair of, are matched and are carried out work respectively by two compression rollers setting up and down.In addition, the first compression roller 4 and the second compression roller 6 also have the effect of traction, and the direction of rotation of two paired the second compression rollers 6 is contrary, and the second compression roller 6 rotations make to move by base material 8 and first compression roller 4 of the second barrier film 10 towards the place ahead in its gap; Same, the direction of rotation of two paired the first compression rollers 4 is also contrary, and the first compression roller 4 rotations make the first barrier film 9, base material 8 and the second barrier film 10 by its gap move towards cutting knife 7 places in the place ahead.In preparation process, can pass through to improve the rotating speed of the first compression roller 4 and the second compression roller 6, and adjust compression pump pressure, to improve the preparation speed of wet method prepreg.
Certainly, except adopting the first compression roller 4 and the second compression roller 6 to draw, can also adopt the draw-gear with draw same as the prior art to draw, this draw-gear is connected with the first barrier film 9, base material 8 and the second barrier film 10, draw the first barrier film 9, base material 8 and the second barrier film 10 towards same direction synchronizing moving, meanwhile, the first compression roller 4 and 6 effects of playing extruding of the second compression roller.
In cutting step, after overlay film, and reach after required size, use the cutting knife 7 of prepreg machine to cut base material 8, the first barrier film 9 and the second barrier film 10, make the prepreg of given size.The prepreg of making is to using base material 8 as reinforcing material; 8 liang of surperficial barrier films of base material can prevent that foreign material from sticking on the colloid on base material 8 surfaces; play the effect of protection, the fabric width of the first barrier film 9 and the second barrier film 10 is equal, and all than the large 40～60mm of the fabric width of base material 8.
In the present embodiment, the fortifying fibre braid that is individual layer for the preparation of the base material 8 of prepreg, the first barrier film 9 is red barrier film, and the second barrier film 10 is blue barrier film, and colloid is resin adhesive.
This preparation technology is applicable to the making of the prepreg of multiple fabric width, but maximum fabric width must not surpass the width of the first compression roller 4 and the second compression roller 6.
